f you don't need serious processing power, the Dell Latitude 10 and ThinkPad Tablet 2 will get the job done and they're crazy light and portable. They also offer twice the battery runtimes of Intel Core i5 tablets like the Surface Pro. It's also worth looking at the HP Envy x2 if you might sometimes need a good keyboard since it comes with an excellent keyboard dock that turns it into a laptop form factor.

Android tablets can certainly play movies, handle word processing, web browsing and have good battery life that's similar to the Intel Atom Windows 8 tablets mentioned here.
